ISO: Looking for a dog trainer who does housebreaking. We have a 6 month old Yorkie who "sort of" has it, but not completely and we are not sure what we are doing wrong. Extensive research online and have done it all: crate training, umbilical cord training, bell training, exercise pen, feed and water on schedule, track her schedule daily, outside every 2 hours...not sure what else we can do!
